Sigma-7 Family of Servo Motors & Amplifiers Raise Bar in Automation Performance

Description

Yaskawa America, Inc. announces the introduction of Sigma-7, a new line of rotary, linear and direct drive servos and amplifiers that bring a new level of operating efficiency to automated equipment.

System designers and automation end users will benefit from the speed, precision and efficiency improvements in Sigma-7, the most technologically advanced servo systems ever created by the world’s largest manufacturer of drives, motion control, and robotics.

Specs

Among Sigma-7’s key advantages:

  • Nearly double the bandwidth of Yaskawa’s industry-leading Sigma-5 servos, for quicker response to system commands
  • 24-bit encoding that boosts precision to a level 16 times higher than the industry standard
  • A 20% smaller footprint, plus a new amplifier design that saves control panel space
  • A new package of algorithms that correct machine imperfections, including ripple compensation, anti-resonance and friction model compensation
  • New dual-axis amplifiers that mount in smaller spaces, cut parts counts and regenerate power for long-term energy conservation
  • Full compatibility with millions of Sigma-5 servos currently in the field, enabling replacement without the need for reprogramming or re-engineering existing equipment
